*PICTURE-FRAME.

SPECIFICATION forming part of Letters Patent No. 649,133, dated May .8,1900.

Application filed September 29, 1899. Serial No. 732,012. (No model.)

T @ZZ whom t may concern,.-

Be it known that I, HAMILTON IRVING MAR- LATT, a citizen of the UnitedStates, residing at Buffalo,in the county of Erie, in the State of NewYork, have invented a new and useful Improvement in Picture-Fram es, ofwhich the following is a specification.

This invention relates to the construction of the small oval andcircular picture-frames which are adapted to receive pictures andphotographs of cabinet size and which are usually gilded.

The object of my invention is the production of a strong frame of thiskind which can be manufactured at less cost than the ordinary Woodenframes and which is not liable to warp, shrink, or crack.

In the accompanying drawings, Figure I is a front elevation of a frameembodying my invention. Fig. 2 is a rear elevation thereof.

Fig. 3 is a horizontal section in line 3 3, Fig. 1.

Like letters of reference refer to like parts in the several figures.

My improved frame consists of' a body or main portion A and a facing B,which may be either plain or ornamented, as desired. The body iscomposed of a strip or band of asbestos board,which is bent in thedesired oval or other form around a suitable form or mandrel, as may bemost convenient. The board which I prefer for this purpose is that knownin the trade as asbestos millboard and is sufficiently pliable to permitof the required bending. The strip is cut from a fiat sheet of suchmaterial, with the grain or fiber running lengthwise of the strip inorder to utilize the` strength of the material to the best advantage.This strip is bent to the desired oval or circular form, and its endsare secured together either by suitable cement or by a mechanicalfastening. Asbestos retort-cement or silicateof soda is satisfactory forthis purpose. The ends d of the strip are preferably chamfered orbeveled and are overlapped, as shown in Fig. 2, to form a strong flushjoint. If the asbestos millboard is not sufficiently pliablek to permitof bending', it is softened by moistening the same with diluted silicateof soda.

The facing B may consist of any suitable plastic material which isshaped tothe desired form in a suitable mold. I prefer to l employ forthe facing a composition composed of a fibrous mineral cement, a mineralfiller which gives body to the composition, and an oily or fattyingredient. An asbestos cement composed of about seven parts, by weight,of sodium silicate, one part of asbestos, six parts of calciumcarbonate,- and five parts of water is very desirable for this purpose.Various substances may be used as the filler-for instance, kieselguhr orinfusorial earth and geyserite, which are silicious substances, talc,Whiting, magnesia, yellow ocher, tripoli, and the like. In preparingythis composition for molding an oily ingredient is added, preferablylinseed-oil or fish-oil, to counteract the tendency of the material tostick to the mold. I prefer to mix the ingredients in the proportion ofabout four pounds of asbestos cement, four pounds of filler, and onepint of oil. After molding the facing B the back thereof is cut orscraped off iiush with the top of the mold, and the frame-body A, whichhas been previously constructed, is cemented at one edge to the flatback of the molded facing, this being done by applying a coating ofcement to one edge of the frame-body and pressing the same against theback of the facing While the same is still in the mold. Silicate of sodaor asbestos retort-cement may be used The molded facing is now Withdrawnfrom the mold by means of the projecting body, to which it is cemented,and the frame is dried by exposing it to the atmosphere for a period offrom twenty-four to forty-eight hours, after which it is subjected to acomparativelyhigh degree of heat in a suitable oven or kiln for asufficient period to harden or bake the molded facing. After hardeningthe facing in this manner it may be gilded or otherwise decorated. Thefacing B may, however, be formed of asbestos board, if desired.

By this construction a strong and durable frame is obtained which can beproduced at much less expense than a wooden frame of the same size.Moreover, the asbestos board of which the body ofthe frame isconstructed and the ornamentation applied thereto are not affected bymoisture, dampness, heat, or cold, and the frame therefore will notwarp, shrink, or crack, nor will the ornamentation crack or check.

for so securing the frame-body to the facing.
